22 Claims.

This invention relates to the molding of counter stilfeners for shoes and more particularly to those made from fiberboard or the like.

The mechanism of this invention is intended pecially to form the stifiener with a downwardly extending marginal bead about the outer edge of the stiffener attaching flange.

one embodiment 0 In t this invention, this bead is formed hollow on its upper face from a stifiener previously molded flat flange itself, may,

to form a flat flange, which if desired, be molded by the same mechanism in a cycle of operations preliminary to that in which the hollow bead is formed.

In another embodiment of this invention a stifiener previously molded to produce the hollow bead is further treated to make the bead of solid cross section.

Fora more complete understanding of this invention, reference may be had to the accompanying drawings in which Figure 1 is a perspective of a last or plug and a flange plate for use in molding the stiffener with a flat flange and thereafter to form a hollow bead in the Figure 2 is a central vertical section through the same showing therein for the firs a stifiener blank in position t molding operation.

Figure 12 is a se machine of a rovided with molding mechato a larger scale tion of the machine of Figure ction on line l2-l2 of Figure 11, but showing the counter in position.

Figures 13, 14 a Figure 12 or portions nd 15 are sections similar to thereof, but showing the parts in successive positions during a molding cycle.

Referring Figures 1 to 5, at I having an end por first to the construction shown in is shown a plug or last block tion 2 of the general shape of the heel end of a last except that the sole simulating face is provided about its margin with an outwardly extending bead 3. At 4 is shown a plate member shaped to engage the sole face 5 of the last member throughout substantially its 5 entire heel end portion inwardly of the bead which passes around the sides and rear end of the plate member 4. As shown this plate memher is carried at the upper end of a standard 6 which passes within a slot 1 in the sole face of 10 the last member, and is shown as hinged as by the pintle pin 8 between spaced portions 9 at the lower end of the member I. When the plate member 4 isbrought up toward the last face 5 the standard 6 throughout substantially itsv en- 15 tire length passes into the slot 1 and is housed thereby. At the lower end of the standard 6 is shown a handle to by which the platemember 4 may be moved toward or from a position adjacent to the last sole face 5.

The last block I isdesigned to have placed over its end portion 2 a counter blank such as l2 shown in position thereon in Figure 2 and by itself in Figure 6. This blank is curved to the general contour of the top and sides of the 25 last member and is so held during the molding operation by any suitable means such as the well known side molds, a portion of which means is shown at 13 in Figure 3, the counter being placed between these parts with its lower margin ex- 30 tending therebeyond as shown at M in Figure 2. The plate member 4 being swung outwardly into the position shown in Figures 2 and 3, a flange wiper l5, which in general may be of well known construction, is passed across the protruding portion H of the counter blank so as to wipe this portion inwardly over the bead 3, as shown in Figure 3, to form an in-turned attaching flange for the counter in the usual manner. By this means the counter may be molded to the proper curvature and may be provided with an inturned substantially flat attaching flange I4 as shown in Figure 7.

If desired, of course, the substantially flat inturned flange might be formed by any other well known mechanism. By whatever means it may be formed initially flat, the mechanism herein shown may be operated so as to produce an outwardly extending hollow marginal bead about the outer margin of the flange. The operations to do this are shown in Figures 4 and 5. The wiper l5 being retracted, the plate 4 is moved toward the last member so that it engages the inturned flange of the counter inwardly f the last bead 3 in the position shown in Figure 4. The wiper 15 is then passed across the outer face of the plate 5 and in order that it may "do so easily it is shown as provided with a roller 16 at its forward end which engages the upper end of the plate 5, and as the wiper descends crowds the plate 5 inwardly toward the last face 5 so as to conform the counter flange to the contour of the bead 3 on the last member and to the sole face 5 of the last member inwardly thereof and adjacent thereto. On retraction of the wiper l5 and removal of the counter it has the general appearance shown in Figure 8.

The counter is then ready for the final molding operation, which consists in compacting the flange material so as to form the outwardly extending marginal bead of substantially solid cross section. The mechanism for accomplishing this is shown in Figures 10 to 15. Referring first to Figure 10, at 20 is illustrated a machine standard or frame of a well known type of counter molding machine. This frame 20 haspivoted at 2! thereto a lever 22 which has pivoted at 23 thereto a table member 24. The table member is also pivotally connected to the frame by a link 25 pivoted at one end 26 thereto and at its other at -21 to the frame 20, so that as the lever 22 is swung about its fulcrum 2! the table 241 is moved up and down in substantially a straight line. A cam carried by a shaft 51 operates through a heavy spring 32 against the lower end portion of the lever 22 so as to rock this lever at suitable times. The shaft 31 also has a crank arm 35 to which is connected a pitman 36 extending to one end of a lever 31 fulcrumed at 38 at the top of the machine. The forward end of this lever 37 is connected by a link 39 to a vertically reciprocable wiper carrier 30. This wiper carrier may carry the wiper 15 shown in Figures 3 and 5, which wiper may also be used in connection with the final molding operation as will later be described. The shaft 31 is rotated in any suitable manner as through the intermeshing gears 41 and 42, the gear 42 being carried by a main actuating shaft 43 driven in any suitable manner. The table 25 has resting thereon a plate (see Figures 12 and 13) from which ber 52 as in the constructions hereinbefore deable sockets 6| in the last member 52 so as to insure a substantially straight up and down relative motion between the last member and the plate 55. The standard 56 passes rearwardly of a cross bar 65 secured at opposite ends to the last member 52 and this cross bar acts on a cam face 61 on the outer face of the standard. A spring 58 secured to the last member 52 bears against the inner face of the standard 56 and presses this standard out against the cross bar 65 as far as is permitted by the cam face 61.

When the last member 52 is elevated with respect to the plate 50, the plate is held outwardly from the sole face of the last member 52, as is shown in Figure 12, and in this position of the parts the counter with its hollow marginal bead 10 may be placed over the upper end of the member 52. Above the member 52 the machine carries the usual side molds I I, shown best in Figure 11, which may be of the usual type, which close together against the counter on upward pressure of the last member with the counter thereon thereagainst. As this is a common construction, no detailed description is believed necessary. The counter being in position over the last member 52,the table 25 preferably having a hinged top to permit the last member and the plate 55 to be swung forwardly as a unit, as shown in dotted lines in Figure 10 to facilitate the placing or removal of the counter,the last member in upright position with the counter thereon is raised by the raising of the table 241 until the counter is engaged by the side clamping members ll which press the counter sides against the sides of the last member 52, stopping further upward motion of the last member.52, spring 51 is compressed as the plate member 50 carrying the standard 56 therewith continues to rise.

The action of the cam face 51 on the cross bar then causes the plate member .55 to move upwardly and inwardly into contact with the inner portion of the counter flange, as shown in Figure 13, and as this motion is continued, it engages the flange material and forces it upwardly, compressing it between the upper edge of the plate member 55 and the outer conforming means 11, as shown in Figure 14. The wiper I5 is then brought down over the outer face of the plate 55, engaging the bead material extending outwardly beyond the edge of the conforming means 1| and the outer face of the plate 55, and compresses this material between these members, as shown in Figure 15, so as to condense the bead into substantially solid cross section, as is shown in Figure 9 at 15. Further operation of the machine causes the wiper E5 to retract and the last member 52 and the plate 55 to descend and separate from each other, whereupon the completely molded stiffener may be removed.

From the foregoing description of certain embodiments of this invention, it should be evident to those skilled in the art that various changes and modifications might be made without depar ting from the spirit or scope of this invention as defined by the appended claims.
